When installing the horizontal stabilizer there are two fittings on the rearand beneath the stabilizer. Two bolts are to pass through one fitting,through the fuselage and through the second fitting. Problem is thefuselage sides are not parallel in this area. I'm trying to figure out thebest way to run the bolts through the two fittings. Do I add wood shims sothe fittings lay flat or do I make wedge shaped washers for under the bolts?Other suggestions?ChrisSacramento, CaWestcoastpiet.com________________________________________________________________________________

Chris I used shims. When making the brackets pay attention to clearances, Iremade a few times! See here http://textors.com/DSCN4190_800x600.jpg Jack TextorDSMNX1929T-----Original Message-----

I don't think it really matters=2C the bolts are in shear=2C there is no real reason that they can't be angled. Having said that=2C the amount it takes to make the fuselage sides parallel is only the thickness of the plywood doubler. I trimmed the plywood=2C so that the sides were parallel=2C in the area under the fittings. BYW=2C my plans show rivets there=2C not bolts. I used rivets=2C and with rivets it really does not matter if the sides are parallel. I chose to trim the plywood because with the fittings on an angle=2C it moved the bolt holes for the stabilizer aft a bit and made them not line up with the holes in the fitting on the vertical fin. Gene do not

Should have used some sort of shims on mine, but sadly, did not. One of the small regrets and costs of "get-done-itis". A lesson for all who are still building. The parts that you rush will always be there to stare you in the face when you are done. It looks a little "off" but It'll never give way I'm sure. Dan HelsperPuryear, TN-----Original Message-----

Chris, I also used shims. I made some shims out of spruce and when I got them to where the surfaces were parallel and glued the shims to the fuselage sides. Chuck----- Original Message -----

#2 Chris, I also noticed on the plans in his book that Bernie calls for rivets rather than bolts on the top side of the stabilizer where the stabilizer is fastened to the vertical fin. I wondered why until I put everything together and found that the nuts on the bolts interfere with the vertical bolts going down through the fitting to the fitting on the lower side of the stabilizer. When I put the plane together for the inspection I'll use hardware store bolts and thin nuts and for the final time after covering, I'm going to use 3/16-inch rivets. C----- Original Message -----

I know it's in the plans, and I know it's been done successfully in the past, andI know that's the way BHP did it... but using rivets in wood just doesn't giveme a warm, fuzzy feeling.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Tue, 14 Feb 2012 18:49:27 +0000 (UTC)

Hi Mike,Looks like someone did a field top overhaul on it. I can see that the cylindersare the old style with the bronze spark plug inserts and it also appears tohave possible cracks that run from the spark plugs to the exhaust seats. Youcan see there is one from each spark plug hole. They could be serviceable. Itwould be worth having them inspected by a shop. Something you could do yourselfis to put some spark plugs in the cylinders and pour some kerosene in them.If the cracks are big or the valves are not seated good you will see the leaks.Keep in mind that these little Cont engines will just keep running andrunning. Not everything needs to be brand new in them. There are serviceablelimits in the overhaul manual. As long as your parts meet those, consider themgood.BTW, My cylinders are also .015 over.
